Gaseous HZnCl has been synthesized for the first time in a high-temperature tube furnace with a D.C. discharge of a flowing mixture of pure HCl and zinc vapor. The vibration-rotation emission spectrum of gaseous HZnCl was measured at high resolution using a Fourier transform spectrometer. The H$-$Zn stretching mode ($\nu_{1}$) of the H$^{64}$Zn$^{35}$Cl, H$^{66}$Zn$^{35}$Cl, H$^{68}$Zn$^{35}$Cl, and H$^{64}$Zn$^{37}$Cl species, as well as the $2\nu _{1} - \nu_{1}$ hot band of the most abundant isotopologue (H$^{64}$Zn$^{35}$Cl) were observed near 1966 cm$^{-1}$. A least-squares fit was performed for each of four observed isotopologues and their spectroscopic constants were determined.
